Another article sent to us from Mark Davis in this he muses reality and quantum physics.

Reality feels very real to me and I’m sure it does to you as well. Some things are nice, some unpleasant. Why would anyone believe for a second that none of this is real? Well, if we look deeper into our perceptions of our world and at the fundamental physics we see certain inconsistencies. Lets first start by looking at how we perceive the world around us and the limits that seem to have been applied to our experience of reality.

We do not see all there is. You do not see infrared light nor do you see UV light. You do not see the electrical activity in the muscles of other animals, yet all these are there in our everyday world to be seen. Other animals see them, so why not us?

Think of the survival advantage to seeing in say, infrared light. If you equate the spectrum of light we see to say the size of a piano keyboard, the keyboard of light we do not see would be long enough to go from earth to the sun and back and that is just the electromagnetic spectrum. We see the world as made up of solid objects; if I kick a wall it hurts my foot. You and I perceive the wall as a hard solid and uncompromising yet, when we look only a bit deeper we find it’s not solid but mostly made up of empty space because our wall is made of atoms and an atom is made of a nucleus surrounded by electrons, both are very small and very far away from each other in fact an atom is 99.999999999999.6% empty space. But you do not experience it as such. Who was it or what was it that dictated it should be so?

Look at a photograph on a computer screen and it looks just like the real world but, again let us look closer, zoom in on one spot of the photograph, and you start to see you start to see it’s made of pixels zooming in more we just see blocks of colour. This gives us no more information and our reality is no different if we look at our atom again we see what it is made of until we get down to the level of quarks super string parts and things at plank length scale. It is at this point we lose all sense of reality and once solid objects just become theoretical concepts just like our block of colour it gives us no more information. It could mean something, it might mean nothing. Do you now see why I equate the two concepts? Both appear to be one thing, yet when we look closer it is apparent they are something quite different.

The most familiar concept of a computer simulation most of us know about, is a computer game. Imagine, if you will,  playing a computer game and in the game you walk down a street. You get to a corner,  you turn the corner and the world is the same, yet what was around the corner didn’t exist until you turned the corner to observe it. In other words it didn’t exist until you observed it, on the computer screen at least. Yes the computer code existed but it was not real on the screen and again the world of physics is no different. If we look at the measurement problem in quantum physics we see that it says that a particle does not exist until its observed by a conscious observer. When the question is asked how in gods name dose a particle know if it been observed or not, no one seems to know.

You and I are made ultimately of energy e=mc2 in other words matter is condensed energy and matter and energy are expressions of information just like the 1 and 0 are an expression of binary code. we seem to live in a pixelated universe in which both energy and matter carry or express information.

In 2012 DR James Gates jr  was working on super symmetry within string theory he found a computer program first written in the 1940s called error correcting code to be an inherent part of string theory in other words a computer code for correcting errors is written into the fundamental fabric of our universe.
